Gallon Jar Pump, 89 mm - Stainless Steel

This stainless steel pump dispenses directly from a 1 gallon (3.8 L) jar with an 89 mm neck opening. You should measure the outside diameter of your jar opening - including the threads, to determine the proper size needed. The stainless steel lid will sit over the jar threads.

The pump dispenses 1 ounce (30 mL) per stroke with the option to reduce portions in 1/8 ounce (3.7 mL) increments, using the supplied gauging collars. When you place your order, be sure to request a colored knob engraved with your contents for a clean presentation. A white knob is shown, however, black is standard.

Trouble shooting a Server Products Stainless Steel Pump when product is oozing out of the locking collar.

Problem:

How do I stop this pump from dripping?

Solution:

To take care of this mess maker, check the seals and o-rings. If they look worn with tiny cracks or are misshapen, it's a good time for replacement.

Problem:

Why is my pump hard to push down for dispensing?

Solution:

This type of symptom was typically seen in Brazed Style (valve bodies) pumps manufactured prior to 1993. Well done on your pump maintenance, if yours is of that age. Our advice is to make sure the ball is resting on the inner valve assembly inside the cage. If that is correctly placed, also ensure the inner valve handle is on the catch.

Problem:

Why does my pump dispense only a little or no product (under dispense)?

Solution:

The next time your pump is apart for cleaning, check all seals and o-rings for wear or damage. Over time they develop tiny cracks and need to be replaced. Further investigation depends on what style (age) your pump is…

For a Cast Valve with Captured Balls (1999 to present) Make sure the balls move freely when cleaning.

A Cast Valve with Loose Balls (1993 - 1999) Make sure the balls are in the proper place; one in the inlet port of the valve body and the other in the discharge port.

For Brazed Valve Bodies (prior to 1993) Make sure a ball is installed beneath the ball-retaining pin, the retaining pin is in place and a ball is resting on the inner valve assembly under the cage.

Problem:

Why is product oozing out around or under the locking collar?

Solution:

First make sure that the seal is firmly installed on the piston and stem assembly, with the flare side of the seal facing down. If the seal was installed properly, it likely needs replacing.

Problem:

Why isn't my pump returning to the top after dispensing?

Solution:

Known to insiders as a plunger problem, it's typically either a missing washer or a broken/missing spring.

The washer is necessary to compress the spring, so if it's missing, your plunger will not return. A well-used spring can become worn out or broken. The spring is also necessary for pump operation. Now you can call yourself an insider too.

Your pump Model and Part number are stamped on the lid. With that information, a parts breakdown will determine replacement part numbers.
